Question

Urea makes up a significant amount of urine, and is the chemical that the body uses to rid cells of unwanted carbon dioxide and nitrogen. the chemical formula is as follows: nh2-co-nh2. how many water molecules could hydrogen bond to urea?

Answer 1

Urea is highly soluble in water. When it is allowed to dissolve in water in the presence of heat, it will yield ammonia and carbon dioxide. The reaction is shown below:

NH2-CO-NH2 + H2O ⇒ 2 NH3 + CO2

As you can observe in the stoichiometric equations, 1 molecule of water can dissolve with 1 mole of urea.
